Description

Fel-Pro FPS62003 Breather Gasket – 5HP Flathead & Raptor Racing Engines


Keep your engine sealed, legal, and race-ready with the Fel-Pro FPS62003 Breather Gasket, designed for 5HP flathead and Raptor racing engines. This high-quality replacement gasket seals the breather assembly to maintain proper crankcase ventilation, prevent oil leaks, and stabilize internal pressure—critical for both reliability and consistent kart racing performance.


Whether you're restoring a vintage kart or maintaining a competitive flathead or Raptor build, this gasket ensures a tight seal under demanding track conditions.


Why the Breather Gasket Matters in Kart Racing

In flathead and Raptor engines, the breather system controls crankcase pressure and oil mist evacuation. A worn or leaking gasket can cause:

  • Oil seepage or blow-by
  • Inconsistent crankcase pressure
  • Loss of performance
  • Messy engine bays and tech inspection issues

The FPS62003 restores proper sealing to keep your engine clean, efficient, and performing at its best.

Maintain Peak Engine Performance

A properly sealed breather system is essential for crankcase pressure control and oil management. Replacing a worn gasket during rebuilds or routine maintenance helps prevent leaks, maintain performance, and extend engine life.

If you’re refreshing your 5HP flathead or Raptor racing engine, the Fel-Pro FPS62003 Breather Gasket is an essential, race-proven sealing component.

This gasket fits the Briggs & Stratton 5HP Flathead engine and Briggs & Stratton Raptor racing engines, including Raptor I, II, and III models commonly used in kart racing and Jr. Dragster applications.


What does the breather gasket do?

The breather gasket seals the breather assembly to the engine block. It:

  • Prevents oil leaks
  • Maintains proper crankcase pressure
  • Supports efficient crankcase ventilation
  • Reduces oil blow-by

A proper seal is critical for both performance and clean race-day operation.


How do I know if my breather gasket needs replacement?

Common signs include:

  • Oil residue around the breather housing
  • Visible gasket damage during teardown
  • Inconsistent crankcase pressure
  • Oil blow-by or seepage

Replacing the gasket during routine maintenance or engine rebuilds is recommended.


Is this gasket suitable for kart racing?

Yes. The FPS62003 is commonly used in vintage kart racing, oval track competition, and Jr. Dragster applications. It is suitable for engines competing under organizations such as NHRA and World Karting Association (always confirm current rulebook requirements).


Will replacing the breather gasket improve performance?

While it does not directly increase horsepower, replacing a worn gasket restores proper crankcase sealing, which helps maintain consistent engine performance and prevents oil-related issues.
